摘要	The electrochemical behavior of SAE-1020 carbon steel in 0.25 M Na(2)SO(4) solution containing different concentrations of H(2)S at 90 degrees C was investigated using the methods of weight loss, electrochemical measurements, scanning electron microscopy (SEM) and X-ray diffraction (XRD). The results showed that the corrosion rate of carbon steel increased significantly with the increase of H(2)S concentration. H(2)S accelerated the corrosion rate of SAE-1020 carbon steel by a promoted hydrogen evolution reaction. Severe corrosion cavities were observed on the carbon steel surface in the solutions containing H(2)S due to cementites stripped off from the grain boundary. The loose corrosion products formed on the steel surfaces were composed of mackinawite. (C) 2010 Elsevier Ltd. All rights reserved.
